PLZ AMWSER, find the area for the circle, will mark brainest, plz tell me what u did to get the ANWSER

area = 81π in² (or ≈ 254.47 in²)

Step-by-step explanation:

The formula for an area of a circle is  area = πr².

You are given the diameter, which is 18 in.

diameter = radius (2)

So to get radius, divide the diameter in half:

18/2 = 9.

Now that we have the radius, put that back into the formula for the area of a circle:

area= π9²

Then, solve for the 9², which will be 81 and put it back into the formula.

area = 81π in²

If you need to get rid of the π, the answer will be about 254.47 in²

sorry not sure

step-by-step explanation:

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
